"The story is similar to Pushmo's, but instead of kids, Mallo must rescue birds. Retrieving them proves to be quite challenging as the gameplay has been completely overhauled since Pushmo. Crashmo puzzles are no longer restricted to back and forth movement. The puzzle area has been expanded considerably and blocks can now be pushed (or pulled) backwards, forwards, and sideways. However, perhaps the biggest change is that unsupported blocks give in to gravity and fall downwards."
